Change in phonon dispersion with pressure

Hi,

I'm looking into how phonon dispersion changes with pressure analytically and need to know how the atomic spacing in copper changes with pressure in order to model the crystal. I can't find any helpful papers online :(

Any help would be appreciated

thanks

For phonon dispersion dependence on pressure, search for the Grueneisen parameters of copper. For lattice variation, search for Birch-Murnaghan equation of state of copper. I'm sure you will find these in literature.
